Advantages/ Disadvantages
Tidal energy is Renewable or Non-renewable
Renewable
Object with blades that turn a rotor to power a generator. They can be placed on the seafloor where there is strong tidal flow.
What are Turbines
The MeyGen project
What is the largest tidal project undergoing production (predicted to generate and store 398 MW)
Year of the earliest evidence of the use of the oceans’ tides for power?
900 A.D.
How can tidal energy benefit the environment?
Tidal energy does not produce greenhouse gases.
What is the minimum range requirement to produce tidal energy economically?
What is a tidal range of at least 10 feet?
254 megawatts
What is the current highest electricity generation capacity?
The sum of the solar and lunar tides and depends on the alignment of the sun and the moon.
What is the total tide
How can tidal energy be bad for the environment?
The turbines used to produce the energy can affect marine life.
A power system that has vertical axis turbines mounted in a fence or row placed on the sea bed
What is Tidal Fence
The Sihwa Lake Tidal Power
What tidal project has current largest output.
The gravitational pull of the moon and sun along with the rotation of the earth create_____ in the oceans
What are the tides
Scarcity of Suitable Locations and high construction costs
what are disadvantages of Tidal energy
Like dams built across tidal rivers, bays, and estuaries to form a tidal basin.
What are tidal barrages
The Sihwa Lake tidal Project Output
What is generates 254 MW
What is the name of Archimedes hydraulic machine that converts the potential energy of water on an upstream level into work
screw turbine
misalignment, imbalance, looseness, broken gear teeth, and bearing defects. Are associated with?
Like barrages in using man-made retaining walls to partially contain a large volume of incoming tidal water, with embedded turbines to capture its energy
What are Tidal lagoons
The Big Cajun
What is the current project collecting tidal and wind energy
self-gravitating, near-resonant, sloshing of water in a rotating, elastic, ocean basin with ridges, mountains, and submarine basins.
